Hi Kristoffer,
Hmmm ... got me beat. I pulled up the "kr_new_asf_asf_t.p3d" file in O2 and it appears fine ....
To me it seems maybe the road tool is defining it incorrectly when the WRP file is being made.
Have you simply tried droping a kr_new_asf_asf_t.p3d object onto the map WITHOUT using the road tool and seeing what it looks like?
Also, for your Visitor reference / preview files, make sure your P: drive (typical), CA directory is using the ROAD files from BIS recently provided source sample files;
